Look Ma, No Hands!
While preparing to celebrate the 81st birthday of this bike, I received this 1939 Shelby Cycle Co. Price List.
Of the lightweight models, there's a P4 Super-Sports Men's Racer - Featherweight crank.
With 22 in. frame, 28x1-1/8" wheels and $24.50 price, that's a good match, but without specs or pictures of a P4, I can only guess.
Compared to the Shelby P1 roadster model, this bike has a similar shape fork (these tips Made in England) and the "Featherweight" crank appears to be a Williams 5-pin (this one has model B.100 inch-pitch).
